Duplex bushes are similar to standard bushes, but are reinforced with an intermediate tube. This bush configuration provides high radial load bearing whilst retaining low axial and torsional stiffness rates.

A semi-bonded bush consists of rubber sandwiched between two concentric steel sleeves. The rubber is bonded to the inner sleeve and interference fitted to the outer sleeve. The semi-bonded bush is designed to accommodate small torsion, conical and axial movements and endure radial loads.

These bushes consist of a contoured inner and outer metal forming a ball-joint, articulated by a thin annulus of rubber. They are designed to accommodate high radial and axial loads and allow conical and torsional displacement and misalignments.

The spring-eye bush consists of rubber bonded to an inner tube and force-fitted into an outer sleeve. The spring-eye bush is similar to the semi-bonded bush series, although the outer metals are turned over to increase radial and axial load bearing capability.
